Application Progress of Hyperspectral Imaging Technology in Rapid Detection of Microbial Contamination in Animal Derived Food

高光谱成像(hyperspectral imaging,HSI)技术作为一种无损、快速、准确的检测技术在动物源性食品微生物污染检测方面得到了广泛应用。该技术集图像与光谱技术的优势于一体,可同时检测实验样品的物理特征与化学特征。本文系统地综述HSI原理,及其在动物源性食品微生物(菌落总数、腐败菌、致病菌)污染无损检测方面的研究进展,指出HSI可以检测出食品中的目标微生物种类和数量,并提出随着光学技术、计算机技术的进一步发展,HSI未来可能的发展方向。

Hyperspectral imaging(HSI) technology, as a non-destructive, rapid and accurate detection technology, has been widely used in the detection of microbial contamination in animal foods. HIS integrates the advantages of image and spectral technology, and can simultaneously detect the physical and chemical characteristics of test samples. This review systematically introduces HSI technology and its research progress in the non-destructive detection of microbial contamination in animal derived food, points out that HSI technology can detect the species and quantity of target microorganisms in food, and puts forward the possible development direction of HIS in the future with the further development of optical technology and computer technology.
